Triggers
Activate on: iCloud full, cloud storage, backup photos, sync between devices, share folder, Google Drive help, Dropbox issues, "where are my files", storage plan comparison.
Scope
This skill covers consumer cloud storage — the services regular people use for photos, documents, and backups.
Not this skill: AWS, Azure, S3 buckets, VPS, Docker, APIs → use infrastructure, s3, or server.
Quick Service Picker
| Your devices | Best fit | Why |
|---|
| iPhone + Mac | iCloud | Native integration, seamless |
| Android + Chrome |
Google Drive | Included with Gmail, auto photo backup |
| Windows PC | OneDrive | Built into Windows, Office integration |
| Mixed devices | Dropbox | Works equally well everywhere |
For detailed pricing and features, see services.md.
Common Confusions
| What you think | What's actually happening |
|---|
| "I deleted it from my phone and now it's gone from my laptop" | Sync works as designed — one file, everywhere |
| "iCloud storage full but my phone has space" |
Phone storage ≠ iCloud storage |
| "My photos are duplicated everywhere" | Multiple services backing up the same camera roll |
| "I pay for 3 cloud services" | Pick one primary, cancel the rest |
Storage Full — What to Do
- 1. Check what's using space — Photos usually dominate
- Empty trash — Deleted files count until trash is emptied
- Disable duplicate backups — Pick one photo backup service
- Offload old files — Move archives to external drive
For service-specific cleanup steps, see cleanup.md.
Backup Strategy
- - 3-2-1 rule: 3 copies, 2 different media, 1 offsite
- Cloud counts as offsite — but also keep a local backup
- Check backup status monthly — don't assume it's working
What to back up and what NOT to store in cloud: see backup.md.
Sharing Files
| Need | Method |
|---|
| Quick share with anyone | Link (set expiration) |
| Ongoing family access |
Shared folder |
| Sensitive documents | Don't use cloud, or encrypt first |
Step-by-step per service: see sharing.md.
Security Basics
- - Enable 2FA on all cloud accounts
- Review shared links quarterly — revoke old ones
- Don't store unencrypted: passwords, IDs, financial documents
触发条件
在以下情况下激活：iCloud已满、云存储、备份照片、设备间同步、共享文件夹、Google Drive帮助、Dropbox问题、我的文件在哪里、存储方案对比。
适用范围
本技能涵盖消费级云存储——普通用户用于存储照片、文档和备份的服务。
不包含以下内容： AWS、Azure、S3存储桶、VPS、Docker、API → 请使用infrastructure、s3或server技能。
快速服务选择器
| 你的设备 | 最佳选择 | 原因 |
|---|
| iPhone + Mac | iCloud | 原生集成，无缝体验 |
| Android + Chrome |
Google Drive | 与Gmail捆绑，自动备份照片 |
| Windows电脑 | OneDrive | 内置Windows，Office集成 |
| 混合设备 | Dropbox | 所有平台表现同样出色 |
详细定价和功能，请参见services.md。
常见困惑
| 你以为的情况 | 实际发生的情况 |
|---|
| 我从手机上删除了文件，笔记本电脑上也没了 | 同步功能就是这样设计的——一个文件，处处同步 |
| iCloud存储已满，但手机还有空间 |
手机存储 ≠ iCloud存储 |
| 我的照片到处都是重复的 | 多个服务同时备份同一个相册 |
| 我付了3个云服务的费用 | 选择一个主要服务，取消其他服务 |
存储空间已满——解决方案
- 1. 检查空间占用情况——照片通常是主要占用者
- 清空回收站——已删除文件在清空回收站前仍占用空间
- 关闭重复备份——只选择一个照片备份服务
- 转移旧文件——将归档文件移至外部硬盘
各服务的具体清理步骤，请参见cleanup.md。
备份策略
- - 3-2-1规则： 3份副本，2种不同介质，1份异地存储
- 云存储算作异地存储——但也要保留本地备份
- 每月检查备份状态——不要默认备份一直在正常运行
需要备份的内容以及不应存储在云中的内容：请参见backup.md。
文件共享
| 需求 | 方法 |
|---|
| 快速与任何人共享 | 链接（设置有效期） |
| 家庭成员持续访问 |
共享文件夹 |
| 敏感文件 | 不要使用云存储，或先加密再存储 |
各服务的分步操作指南：请参见sharing.md。
安全基础
- - 在所有云账户上启用双重认证
- 每季度审查共享链接——撤销旧的链接
- 不要存储未加密的内容： 密码、身份证件、财务文件
